3.3V TTY Serial Port

You will need a TTL-Serial cable. I use an adapted Nokia CA-42 USB to TTL-Serial cable, but you can use whatever cable you want/have.
These little serial cables come in handy when working on embedded boards like this.
Here is some information on how to make a CA-42 into a USB to TTL-Serial cable.
The wire colors may be different, so be careful!

You only need to connect the RX, TX, and Gnd. NOT THE 5Volt pin. CAREFUL!!

             CN4     |    '---------'

Tips

• When connecting the TTL cable try reversing RX/TX if you don't get the console.
• You can remove the top cover by pulling on it firmly to expose the inner PCB. Details in this video by b-rad: http://b-rad.cc/binaries/WDTV.Shell.Removal.AVI
